Description and Introduction

Switched Capacitor Voltage Converter The LM2765M6X is a switched capacitor voltage inverter manufactured by National Semiconductor (NSC). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** National Semiconductor (NSC)  
- **Category:** Power Management IC  
- **Type:** Switched Capacitor Voltage Inverter  
- **Input Voltage Range:** 1.8V to 5.5V  
- **Output Voltage:** -Vin (Inverted Input Voltage)  
- **Output Current:** Up to 50mA  
- **Switching Frequency:** 450kHz (Typical)  
- **Efficiency:** Up to 96%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-6  

### **Descriptions:**  
The LM2765M6X is a high-efficiency, switched capacitor voltage inverter that generates a negative output voltage from a positive input supply. It uses a charge-pump architecture to invert the input voltage with minimal external components, making it suitable for space-constrained applications.  

### **Features:**  
- **Low Quiescent Current:** 100µA (Typical)  
- **No Inductors Required:** Uses only flying capacitors  
- **Low Output Impedance:** 6Ω (Typical)  
- **Automatic Power-Save Mode:** Enhances efficiency at light loads  
- **Short-Circuit Protection:** Built-in protection against output shorts  
- **Small Footprint:** SOT-23-6 package for compact designs  

This information is strictly derived from the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

Switched Capacitor Voltage Converter

Alternative Part Number

  • TPS60500DGSR --: Pin-compatible switched-capacitor voltage converter in the same family lineage; TI acquired National Semiconductor, so this is a direct functional replacement with similar input/output range.
  • MAX1682EUK+T --: Switched-capacitor voltage doubler/inverter in SOT-23-6 package offering comparable functionality and compact footprint for LM2765 designs.
  • LTC1515CS8-3.3 --: Regulated switched-capacitor converter with wide input range and low quiescent current, suitable as a functional substitute where board space allows an SOIC package.
  • ICL7660ACBAZA --: Classic switched-capacitor voltage converter with similar operating principle and current capability, useful as a low-cost alternative.
  • MAX660CSA+ --: Well-known charge-pump voltage converter offering comparable conversion capability and a different series naming.
  • ICL7660SCPAZ --: Classic CMOS charge-pump converter with similar voltage conversion role and broad second-source availability.
